You can tell, even now, where somebody made a last stand. You’ll be walking through mostly intact buildings, and you’ll start seeing bullet holes. There’ll be scorch marks, too, sometimes, where a surface has been protected from the weather. Then further in there’ll be a ring of buildings gutted by fire and riddled with holes, empty husks, sometimes just the foundations. In the middle of it all will be one intact building. That one will be boarded up, reinforced, an ersatz fortress. There’ll be a breach somewhere, of course. Inside, you won’t even find bones; but you will find supplies.
